11 Claims. (Cl. 292-169) This invention relates to a holding and locking device. More specifically it relates to a door lock for an automotive vehicle.

Locks are known that involve locking by displacement of an intermediate member to an inoperative position in which it does not transmit movement of a handle control member to a door bolt and also involve prevention of accidental lock-out by the return` of the intermediate member to operative position through retraction of the bolt caused by closing of the door. I have invented a construction that incorporates the intermediate member as described above and prevention of accidental lock-out to a door lock of the type having a bolt retractible only on opening and not on closing of the door.

An object of the present invention is to provide improvements in a door look of the type that effects locking by shifting an intermediate member to an inoperative position and thus prevents motion of a control member from being transmitted to a door-holding means. More specifically, the lock may be of the type in which the holding means may be suitably actuated on closing of the door to prevent accidental lockout and to permit deliberate lock-out.

A further object is to provide an improved door lock of' the type that has a holding means retractible only on opening of the door and not on closing. The lock may include suitable means for preventing accidental lock-out and permitting deliberate lock-out. Y

Another object is to make improvements in a door look of a kind electing locking by shifting an intermediate member to an inoperative position and having holding means preventing accidental lock-out and permitting deliberate lockout.

Other objects will appear from the disclosure.

The reference character I0 designates a vehicle door having a flange II for the lower side of a door vvindovv,l not shown, and an edge flange l2. To theedge ange l2 is secured by means oi screws I2'==a flange; I3 rof a mounting plate I4, the main body portion of which extends at right angles to thefiange I3 and'to the end flange I2 ofthe door t. A bolt I5 is composed of a block member I6 and an elongated sheet metal member Il attached 'to the block member by rivets I 8. The bolt I5 is urged to the right as viewed in Fig. 1 by means of a spiral return spring I3a sesecured as indicated at I8b to the mounting plate I4 and acting against one end of the bolt block I6; The block member I6 projects through and is supported by openings in the end flange I2 of the door and the flange I3 of the mounting plate I4. An upper inclined surface IBC on the block member jl of the bolt is engageable with a catch I9 (see Figure 6) mounted on a pivot 20. The catch` 4I3 isl urged vdownwardly as viewed in Fig. 6 by a spring 2I and is positioned in a housing 22 fastened to a door pillar 23. The bolt block iwhas a lower inclined surface 24 engageable with asafety catch 25, mounted on the door pillal` 23 by a pivot 26. Catch 25 is urged upwardly by a ycoil spring 21 and is positioned in a housing 28 attached to the door pillar 23. The sheet metal member il of the bolt l5 has an elongated slot 23 receiving the body of a rivet 3! attached to the mountingrplate lf3. The rivet provides sliding support for the left end of the bolt I5. kThe sheet metal member l1 is maintained in spaced relation to the mounting plate I4 at its right end as viewed in Fig. l, by the block I6 to which it is secured and at its left end by a bearing block 3l appropriately secured to the mounting plate I4. A rivet 32 on the left end of the sheet metal member IT of the bolt I5 is received in an elongated slot S3 formed in one end of a link 34. The other end of the link 34 is suitably connected to an inside control handle 35. The left lend of the member I'I is formed with a projection or shoulder 36 having inclined surfaces 3'1 and 38 and a vertical surface or shoulder 39. The shoulder 39 is engageable with one end of a horizontal flange 40 formed on the top and adjacent the left end of an intermediate member 4i. The intermediate member 4I carries a rivet 42 received in an elongated slot 43 formed in the mounting plate I4 and has a vertical flange 44 at its right end engaged at its inner side by a spiral return spring 4 5 attached as indicated at 46 to the mounting plate I4. The cuter side of the flange 44 on the intermediate member 4I is engaged by a roll-back 41. The roll-back is secured to a square shaft 48 to which is also secured an outside control handle 49. The intermediate member 4| has an elongated slot 59 receiving a rivet 5I secured to a control part comprising pivoted plate 52. The pivot for the plate 52 is constituted by a rivet 53 secured to the mounting plate I4. An extension 54 is secured by rivets 55 to the pivoted plate 52 and has a flange 56 engageable with the right end of the link 34. An over-center coil spring 51 connected at one end to the pivoted plate 52 and at the other end of the mounting plate I4 tends to maintain the pivoted plate 52 either in the position of Fig. 1 or in the position of Fig. 3. An elongated slot 58 formed in the pivoted plate 52 and a rivet 59 received in the slot 58 and secured to the mounting plate I4 combine to limit the angular movement of the pivoted plate 52 about the rivet 53. A vertical rod 6l) projects through a flange 6I formed on the pivoted plate 52 and by means of opposite portions 62 formed on the rod and a Cotter pin 53 passing through the rod is enabled through its own vertical movement to control the position of the pivoted plate 52. The rod 69 projects through the flange I I on the door I Il and has at its upper end a push button 64. A rod-like spring 65 is secured generally at one end by parts 66 and 61 to the pivoted plate 52 and carries at its other end a striker 68 engageable with inclined surfaces 69 and 'I9 formed on a projection 'II secured by screws 'I2 to the door pillar 23. The pivoted plate 52 has a re-entrant follower portion 'I3 adapted to be engaged by a cam 74 fixed to a square shaft I controlled by an outside key 16.

y When the above described parts are in the position of Fig. 1 the door I9 is held shut, since opening of the door would involve movement of the bolt block I5 to the right, as viewed in Fig. 6 and this cannot take .place because the catch I9 prevents such movement. In the position of Fig. 2 the bolt I5 is shown in retracted position, this yposition having been brought about by actuation of the outside control handle 49 acting through the square shaft 48 to shift the roll-back il in a counterclockwise direction from the position of Fig. l.

member 4i, and by virtue of engagement of the flange 4B on the intermediate memberr with the shoulder 39 on the sheet metal member I1 of the bolt I5, the bolt l5 moves leftward to the nonholding position of Fig. 2. shown, the bolt I5 may also be moved to the left by suitable actuation of the inside control handle 35, which brings about leftward movement of the link 34, engagement of the right end of the slot .'i with the rivet 32, and leftward movement of the bolt I5.

When the door is to be locked from the inside, downward pressure is applied against the push button 64, which is inside of the window glass, not shown, to cause downward movement of the rod 59. This brings about a small clockwise angular movement of the pivoted plate 52 about the rivet 53 from the position of Fig. 1 to that of Fig. 3. The rivet 5I on the pivoted plate 52 acts against the slot in the intermediate member 4I to move the left end of the intermediate member down to the position of Fig. 3. Now if the outside control handle 49 is actuated to move the roll-back 47 in a counterclockwise direction,

Such shifting of the roll-back produces leftward movement of the intermediate lil Although it is not 4 the resulting leftward movement of the inter= mediate member 4I is Without effect upon the bolt I5. This is due to the fact that the iiange 4I! on the intermediate member has been depressed sufliciently that it does not engage the shoulder 39 on the bolt I 5, butl merely slides down the inclined surface 3l to the position of Fig. 4. When the intermediate member 4I is to be returned from its inoperative lposition of Fig. 3 to its operative position of Fig, 1 in order that the door may be opened by actuation of the outside control handle 49, the push button 64 is grasped and the rod 66 is raised, causing return of the intermediate member 4I to the position of Fig. 1.

The intermediate member 4I may also be brought to its inoperative position of Fig. 3 by means of the inside control handle 35. This handle is suitably actuated to cause a rightward movement of the link 34 resulting in engagement of the right end of the link 34 with the flange 56 on the extension piece 54 attached to the pivoted plate 52. The result is the slight clockwise movement of the pivoted plate 52 to the :position of Fig. 3 and the movement of the intermediate member 4I to its inoperative position.

Let it now be assumed that the door is open and that the intermediate member 4I is in the yinoperative position of Fig. 3.

If then the rollback 4l is left in the position of Fig. 3 and the door is closed, this action will cause the striker 68 to engage the inclined surface 69 on the projection 'I I, thereby lifting the striker. The striker acting through the rod-like spring 65 urges the pivoted plate 52 counterclockwise to the position of Fig. 1, thereby causing a turn of the intermediate member 4I to operative position. In this way accidental lockout is prevented.

If a deliberate lockout is desired, the door is opened, the intermedi-ate member 4I is brought to the inoperative position of Fig. 3 either by actuation of the inside control handle 35 or by depression of the rod 60, and thereafter the outside control handle 49 is actuated to shift the roll-back 4l in a counterclockvvise position from that of Figs. 1 and 3, all as shown in Fig. 4.

Now as shown in Fig. 4 the left end of the intermediate member 4! is both depressed and shifted tc the left so that it engages the `point of blocking shoulder projection 35. Now when the door is closed and -asa result the striker 68 is raised as it passes over the inclined surfaces 69 and Ill the rod-like spring 55 connecting the striker and the pivoted plate 52 lexes and permits the pivoted plate to remain as shown in Fig. 4, the engagement of the intermediate member 4I with the end of the projection 36 maintaining the pivoted plate 52 in the position of Fig. 4 in spite of the upward urging of the pivoted plate by the leverage applied to spring 65 through striker 68. After the door has thus been shut, the parts assume the locking position of Fig. 3. Unlocking may be eifected by lifting of the vertical rod 60. This lifting of rod 69 will, of course, have to be accomplished by someone inside the car for it is assumed that the push button 64 is positioned inside of a closed door Window.

The door may also be unlocked by actuation of the key 'I5 acting upon the square shaft I5 to rotate the cam 14. The lock in which the key 'I5 operates is not shown in detail since it forms per se no part of the present invention. It is sufficient to state that the lock will be of the type requiring a complete revolution of the key I6 in one direction for locking before it can be withdrawn from the lock and a complete revolution in the other direction for unlocking before it can be withdrawn from the lock, with appropriate stops to limit the movement ofthe key in either direction after a complete revolution in that direction. given a complete revolution in the proper direction to effect a complete revolution of the shaft and the cam ld in a clockwise direction as viewed in Fig 3. The cam 1li in its complete revolution will engage the upper side of the reentrant follower portion 13, causing the return of the pivoted plate and the intermediate member lil to the operative position of Fig. l. The door may be locked by a complete revolution of the key 16 causing a complete revolution of the shaft 'l5 and cam 14 in a counterclockwiseA direction as Yviewed in Fig. l. The cam 14 in its counterclockwise revolution will engage the lower side of the re-entrant follower portion 13, causing movement of the pivoted plate yand the intermediate member lil to the inoperative position of Fig. 3.

If the door is closed and locked either by the push button 511 or by the inside control handle or by the outside key '16, unlocking of the door may, of course, be eiected by any one of the last three mentioned means. If now the inside control handle 35 is appropriately actuated the link 34 will be moved to the left, carrying with it the bolt I5 to non-holding position. The door may now be opened and as this takes place the striker 68 moves to the right as viewed in Fig. 6, up the inclined surface 1S. This upward movement of the striker causes the rod-like spring 65 to urge the pivoted plate 52 and the intermediate member 4I back to the operative position of Fig. l.
